THOMAS C. CLARKE, OF CAMDEN, NEW JERSEY.

HYDRANT-FILT'ER.

Speccation of Letters Patent No. 13,027, dated June 12, 1855.

To all whom t may concern Be it known that I, THOMAS C. CLARKE, of thecity of Camden and State of New Jersey, have invented a new and usefulImprovement in the Construction of Hydrant- Filters; and I do herebydeclare the following to be a full, clear, and exact description of thesame, reference being had to the annexed drawings, making a partI ofthis specification, in which- Figure l represents a perspective view andFig. 2 represents a vertical section of my improved filter as attachedto the pipe of a common hydrant.

In a former specification I described an improvement in filters in whichthe force or pressure of the running water acted against a spring andopened a lateral passage for the water through the filter and as soon asthe water ceased to run, the spring reacted and opened a plug valve inthe bottom of the lter and permitted the sediment and dirty waterto'pass out below. This arrangement however, required a separate faucetto be placed in the pipe above the lter and depended for its actionsolely on the spring. In my present arrangement I have combined thefaucet and filter together in such a manner that the single operation ofopening the faucet simultaneously puts the filter in operation and theclosing of the faucet simultaneously opens a waste passage for thesediment and wastings of the filter.

In the accompanying drawings A is a screw attachment to connect myfaucet filter with a supply pipe.

B is a puppet valve attached to the upper end of a vertical stem or rodC. D is another puppet valve attached to the lower extremity of the samevertical stem C. When the valve B rises from its seat it opens a passagearound B for the water from the pipe A into the interior cavity L M.

L M is an enlarged cylindrical chamber attached to the supply pipe Aabove and having a passage at H for the water to be drawn off at.

E, E, is a thin wire cylinder extending from the top to the bottom ofthe interior of the chamber L M and being about one half of the diameterof L M. This wire gauze separates L M into two chambers b and e. b isoccupied by the water and e by sand or other ltering material.

At K a thread or male screw is cut on the vertical rod C and this worksin a female screw at 7c 7c. The valve B and the valve D are so attachedto the rod C that when C is elevated B rises from its seat and opens apassage around B and at the same time D rises against its seat F F andcloses the passage around D, and when C is depressed B falls on its seatand closes the water passage around B and D falls from its seat andopens the water passage around it. The rod C is raised or depressed bythe male screw K turning in the female screw in 71; k and the rod C isturned by the key or lever I.

The operation of the improved faucet filter is as follows: The waterenters through the pipe A. When the key 0r lever I is turned to theright the rod C turning in the screw at 7c rises and opens a passage atB for the water to pass into the filtering chamber L M. The sameoperation of the rod C by the key I closes the aperture at F and thewater having no other mode of escape is forced through the filter E and'passes out at H. Whenever the water is to be stopped olf at H the key Iis turned to the left, this depresses the rod C thus closing the passageat B and preventing the entrance of water there and at the same time thepassage at F is opened and the sediment and washings on the inside ofthe lter are carried out at F.

The rod C instead of being raised and depressed by turning in a femalescrew at 7c 7c may be raised and lowered by a lever or equivalent deviceor the plug valves at B and D may be perforated so that by turning therod C in a horizontal plane a similar result may be obtained or the rodC may be fixed to the chamber L M and made to revolve with it and thusthe rod C be raised or depressed.

Having thus described my improvement what I claim as my invention is-The combination of the filtering chamber, the rod C and the valves B andD whereby the single operation of starting the water brings intooperation the filter and the stopping off the water opens the escape forthe sediment.
